UNSPSC 31163003: Metallic couplings

UNSPSC 31163003 Metallic couplings is a Commodity code that covers metal coupling components used in water and wastewater infrastructure systems, based on recent state and local procurement activity. The code encompasses stainless steel bypass spools, stainless steel tailpieces, ductile iron flanged fittings, straight water meter couplings, and related metallic joining components for water distribution, treatment, and sewer operations. Issuing bodies include municipal water and utility authorities, county utilities departments, and cooperative purchasing programs representing multiple municipalities. Water utilities dominate the buying pattern — the City of Phoenix Water Services Department, Volusia County, the City of Phoenix Water Services Department again, and the Jackson County Utility Authority appear in recent solicitations — alongside county public works and regional cooperative purchasing groups serving highway and water infrastructure needs across multiple jurisdictions.

Recent activity spans California, Massachusetts, Georgia, Arizona, and Florida. Representative opportunities include the City of Phoenix Water Services Department soliciting stainless steel bypass spools, stainless steel tailpieces, and ductile iron flanged fittings (IFB-26-0112, response due November 12, 2025) and the City of Phoenix again soliciting water pipe and miscellaneous fittings including couplings, with quantities up to 21,000 units for straight water meter couplings (IFB-26-0217, response due February 19, 2026). The Berkshire Regional Group Purchasing Program (BRGPP) included culvert products as one category in its multi-category highway supplies cooperative procurement for 32 Massachusetts municipalities (FY27-04, response due April 2, 2026). Jackson County Utility Authority in Florida requested written quotes for materials for a septic abatement project with BABA certification required (response due July 8, 2026). Contracts are typically five-year terms with as-needed supply arrangements, firm pricing for initial periods, and compliance with AWWA, ASTM, and ANSI standards for potable water components. DBE participation requirements and local business preferences appear in municipal procurements.
